FAQs
The 85100AC2236SY50 uses a square flange receptacle configuration with a straight backshell and 36-position cavity. Ensure panel cutouts match shell size 22 and attach using the supplied adaptor backshell. Use the 1/3 bayonet coupling for secure mating, verify solder cup terminations are clean, and route the harness to minimize strain. This reduces installation time and improves vibration resistance in demanding environments.
The assembly supports -40 °C to 125 °C operating temperatures, compatible with harsh environments. It uses socket (female) solder cup contacts, with 36 contact positions arranged in a 36-layout. This combination enables dense power and signal termination while maintaining reliable electrical performance in extreme conditions.
Yes. The 85100AC2236SY50 is MIL-DTL-26482 SI qualified, designed for aerospace and demanding industrial automation harnesses. Its aluminium shell, cadmium plating, and 1/3 bayonet coupling support reliable mating, resistance to vibration, and ease of field maintenance, making it a strong choice for both aircraft and rugged factory environments.
This receptacle carries MIL-DTL-26482 SI qualification and REACH compliance, indicating suitability for regulated environments and reduced environmental impact. Cadmium plating provides corrosion resistance, while the aluminium shell offers lightweight durability, aligning with industry expectations for high-reliability, compliant connectors.
Maintenance is straightforward due to solder cup terminations and a durable aluminium shell with cadmium plating, which lowers corrosion risk. The quick-mate bayonet coupling reduces downtime during maintenance, while the 36-contact arrangement enables high-channel density, delivering higher system efficiency and lower total cost of ownership over the product life cycle.
